Enum DatumParams 

pub enum DatumParams {
    Param3(f64, f64, f64),
    Param7(f64, f64, f64, f64, f64, f64, f64),
}

Datum Parameters can be either 3 or 7

Variants

Param3(f64, f64, f64)

3 parameter datum (translate-x, translate-y, translate-z)

Param7(f64, f64, f64, f64, f64, f64, f64)

7 parameter datum (translate-x, translate-y, translate-z, rotate-x, rotate-y, rotate-z, scale)

Implementations

impl DatumParams

pub fn to_vec(&self) -> Vec<f64>

Returns the datum parameters as a vector

pub fn from_vec(v: Vec<f64>) -> DatumParams

Given a vector of datum parameters, returns a DatumParams

pub fn is_wgs84(&self) -> bool

Check if the datum is WGS84

pub fn to_wgs84<P: TransformCoordinates>(&self, p: &mut P)

Geocentric to WGS84 pj_geocentic_to_wgs84( p ) p = point to transform in geocentric coordinates (x,y,z) point object, nothing fancy, just allows values to be passed back and forth by reference rather than by value. Other point classes may be used as long as they have x and y properties, which will get modified in the transform method.

pub fn from_wgs84<P: TransformCoordinates>(&self, p: &mut P)

Geocentric from WGS84 pj_geocentic_from_wgs84() coordinate system definition, point to transform in geocentric coordinates (x,y,z)

Trait Implementations

impl Clone for DatumParams

fn clone(&self) -> DatumParams

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DatumParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DatumParams

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DatumParams

fn eq(&self, other: &DatumParams) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for DatumParams

fn partial_cmp(&self, other: &DatumParams) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
